<h3>What are Isomers ?</h3>

Isomers are compounds which have same empirical formula , same number of atoms are present but they have difference in arrangement if the atoms.

It is given that

There are four cis, trans isomers for 2-isopropyl-5-methylcyclohexanol

the cis, trans designations of the substituents are made relative to the oh group

PLEASE HELP!! WILL MARK BRAINLIEST

Answer:

The answer to your question is below

Explanation:

                                         Trial 1                   Trial 2

mass of Mg                      0.255 g                0.353 g

mass of MgO                   0.418 g                 0.576 g

Chemical reaction

                                2Mg(s)    +  O₂(g)     ⇒   2MgO(s)

Question 1.

Atomic mass of Mg = 24.31 x 2 = 48.62 g

Molecular mass of MgO = 2(24.31 + 16) = 80.62 g

Trial 1

                          48.62 g of Mg ----------------- 80.62 g of MgO

                          0.255 g            ----------------   x

                          x = (0.255 x 80.62)/48.62

                          x = 0.422 g of MgO

Trial 2                48.62 g of Mg ----------------- 80.62 g of MgO

                          0.353 g            ----------------   x

                          x = (0.353 x 80.62)/48.62

                          x = 0.585 g of MgO

Question 2

Trial 1          

Percent yield = 0.418/0.422 x 100 = 99%

Trial 2

Percent yield = 0.576/0.585 x 100 = 98.5%

Question 3

Average = (99 + 98.5)/2

              = 98.75%

What is the concentration in M) of hydroxide ions in a solution at 25°C with pH 4.1537 (A) 4.15 (B) 9.85 (C) 1.42-100 (D) 7.03*1
natka813 [3]

Answer:

The correct answer is option 'E': None of the above.

Explanation:

Given that pH of the solution is 4.1537

From the basic relation of acids and bases we know that

pH+pOH=14\\\\\therefore pOH=14-pH\\\\pOH=14-4.1537\\\\\therefore pOH=9.8463

From the definition of pOH we have

pOH=-log[OH^{-}]

where

[OH] is the concentration of hydroxide ions in moles/Liter (M)

Applying values and subsequently solving we get

9.8463=-log[OH^{-}]\\\\\therefore [OH^{-}]=antilog(-9.8463)\\\\\therefore [OH^{-}]=10^{-9.8463}M

\therefore [OH^{-}]=14.246\times 10^{-11}}M
